WL8-3917 PP Watch Case

The interior measures 355*240*155 mm and the exterior 385*295*170 mm, with a 35 mm lid depth, a 120 mm base depth, a 5 mm wall and a net weight of 2330 g. The 5 mm wall is the defining feature of this model: greater rigidity means the shell is far less likely to distort under heavier loads or after repeated handling. With a concentrated load, use thicker foam and keep the weight centred for easier hand carrying and vehicle transport.

The closed case is rated IP67 for water and dust protection, covering rain, dusty conditions and short immersion, and keeping contents free of moisture and particles. The shell is injection moulded in polypropylene with a sealing structure, and the thicker wall helps hold seating pressure between the lid and the gasket. We do not claim military standard certification for this model. Inspect the gasket periodically and dry the shell and latches after rain or immersion.

A thicker wall raises shell rigidity and reduces distortion under load, so the lid keeps a more stable seat on the gasket and the IP67 protection stays consistent over a long service life. It also resists knocks and compression better, which suits precision instruments, heavier tools and equipment that is transported repeatedly. The trade-off is weight at 2330 g. If lower weight matters more, choose a 3.3 mm wall model from the same series.

It suits precision instruments, measuring tools, heavier hand tools and accessory bags, and is also used for watches, electronic devices and photographic or drone gear. The 355*240*155 mm cavity works with divided foam to fix each item, the 120 mm base depth lets the main item sit low in the case, and the 35 mm lid depth carries cables and slim accessories.
